Serial No. 405031.

This invention relates to i ulp beaters, eX- tractors and cleaners andelongs particularly to unit machines for kindred purposes in themanufacture oi' paper.

An object of this invention is to construct as a unit not only a breakerbeater, but also a settling trough and thickener, which will eliminatethe elaborate systems such as are disclosed in certain patents of theUnited a@ States. In other words it is an object of thisinvention to.accomplish the same result in a single unit machine as is nowordinarily. attained by a series of individual units connected together.In some apparatus of the Els nature herein mentioned the settlingtroughs are one hundred to one hundred and fifty feet in length. Thereason for making such troughs of that length, apparently extreme, isthat when the beater is started up, say Monsa day morning, and the stockdiluted to about one-half of one per cent to allow the heavy particlesand materials such as sand, dirt and even paper clips and the like tosettle out, the first ten feet of the settling trough collectssubstantially most of such foreign matter. After arun of about one daythis first ten feet of the trough is completely iilled with this dirt,sludge and the like so that the stock coming into the trough simplypasses over that accumulation and settles out further down the trough.By the end of the weeks runApractically no dirt is settled out in thefirst few feet of the trough, andy batlies are introduced at the cxtremeend of the trough to collect such unsettled4 materials.

By the construction and arrangement of parts as shown in this inventionit is sought to provide an 'arrangement of battles or sand settlingcompartments provided with receptacles the bottom portions of whichtaper downwardly as set forth, andare furnished with removable bottomsof any selected tormation and operation. ltlormalls the bottoms ot thereceptacles are open, ti e closures having been removed, and in this waythe iirsttew sandvboxes collect usually the greater amount of refuse,which settles down through the open bottoms of the receptacles into fixecompartment below. As this heavier material 50 settles it displaces thelighter stock and water and eventually iills the compartments below thesand receptacles. When this condition of settlement is reached, theremovable bottom of the receptacle or receptacles is reseated to closethe open bottom, and the compartment below is then accessible forcleaning out the refuse collected in the compartment without shuttin themachine down, as the diluted stock will simply by-pass the com partmentwhich is being cleaned out. It is a further object of this invention toequip each compartment with an easily removed or opened and closedwatertight door, so that the operation of cleaning out the compartmentmay be accomplished as quickly `as practicable. Only one of thecompartments need be cut out of service at any one time. It is intendedthat if necessary this cleaning procedure may be undertaken once ortwice a day, and in this manner the undesirable eX- treme length of thesettling trough can be obviated successfully.

It is also an object of this invention to combine as herein shown anddescribed a long wire net covered cylinder mould similar to standard wetmachine types for thickening the dilute stock, all off which can bebuilt into the single unit machine; A pump is shown in this applicationand adapted tor drawing oli the wat-er trom the inside of the cylindermould and returning the so-called white water back to the mixing chamberor into the beater tub where desired. The thickened stock leaves themould by way' of a couch roll from which it is scraped oil and dis.charged to a chest or to other reiining equipment the same as is thecommon practice with wet machines.

The special construction and arrangement of the various parts of theunit machine comprising this invention are illustrated in theaccompanying"drawings, of which Fig. l represents a side View partly invertical section, and showing all parts assembled. Fig. 2 is a. verticalcross section of one of the settling compartments. and the taperingreceptacle therein showing the removable bottom ot the receptacle, andthe hook rod ordinarily cmployed to take the bottom out and to replaceit. Fig. 3 is a vertical cross section of part of the mixing chambershowing the vertically extending director plate which is located inproximity to the beater roll, and illustrating also the gears, gearshaft and handwheel for moving the adjustable gate or slidel of thedirector plate. Fig. 4 is a top view of the parts set out in Fig. 1.Fig. 5 is a fragmentary vertical and longitudinal section transverselyof the beater roll shaft, showing perforations in the 'up curve of thedirector plate, and setting out likewise a per'- orated beater platebeneath the beater roll covering a chamber opening into the mixingchamber. Fig. 6 is a fragmentary top view showing a screen arranged atthe curve of the inner wall of the tub. Fig. 7 is a fragmentary verticalsection to show the breaker roll provided with an extractor hood toreceive pulprthrown off by the breaker roll of suiiicient ineness topass the perforations. In Fig. 7 also is shown the slice partitionexhibiting the openings or recesses therein and theplates for,controlling the extent of the open recesses in practice. In Fig. 7 isset t'orth also a representation of the pipe for conducting materialJfrom the -breaker roll extractor hood into the tub near the beaterroll. Fig. 8 is a top view-of the parts shown.

in Fig. 7, Withthe hood extractor chamber shown in section. The pipe forconducting the fluent material from the extractor hood to the tub nextto the beater roll is also illustrated inFig. 8. Fig. 9 is an endportion of the movable part of the slice partition, and sets out theadjustable plates which are used to control the size of the recesses inthe plates, and the clamps-for securing the plates are indicated. Fig.10 is a side view partly sectional showing a bladed auxiliary roll totake beaten stock From the beater roll.

Throughout the'drawings and description the same number is used to referto the same part.

Considering the drawings, upon a suitable base 1 the tub 2 is erectedand provided with a midfeather 3 of any chosen form and extent. A rollshaft 4 carries a beater roll 5 and a breaker roll 6, the beater rollbeing of larger diameter than the breaker roll. Ordinarily a. hood 7coversl the rolls, and the rolls are combined in one as set forth. ,Thebreaker roll may be of standard construction with approximately twentyflybars, whereas the beater roll would be ot larger diameter with agreater number of bars spaced closer together,since it is not necessaryto produce circulation by the beater roll. In proximity to the beaterroll is an upwardly curving and extending plate, termed for the purposeso'f this description a director plate, since it directs the beaten stockupwardly to the opening 10 controlled by the sliding gate 11 actuated bysuitable racks and gears l2 on cross shaft 13. revolved by handwhccl 14,as best shown in Fig. 8. The construction and of this arrangement is inpracticetoholdback a considerable quantity Iot" the stock in the beaterroll chamber by means of the adjustable opening marked 10, and onlypermit enough stock to pass into the mixing chamber 4 adjoining t-heplate 9 as would be required for the setproduction from the machine. Therest'of the stock would continue over the roll and under the roll uponthe bed plate tor further treatment. As shown in Figs. 1 and 5 a doctor15 directs the material thrown olf by the beater roll through theopening 10. It is believed to be within the purview of this invention touse any construction o t doctor device.

As delineated in Figs. 1, 4, 7 and 8 this invention includes a slicepartition made up of a lower and fixed part 16, and an upper part 17movable with respect tothe lower part, by means of the adjusting screws18 and handwheel nuts 19 supported by the cross bars 20. As bestillustrated 'in Figs. 7 and 9, the upper and movable part 17 of theslice partition has a number of openings 21, and the sizes of theopenings are governed by the sliding plates 22 secured byl clamps orscrew buttons 23. This invention is in no sense limited to the platesand the clamps for adjusting the open area of any recess 21, as thosedevices are susceptible of various modification.

In Figs. 4 and-8 is shown an ordinary backfall in proximity to thebreaker roll 6.

Considering Figs. 1 and 4 there will be noted next rthe upwardlyextending plate 9 a mixing chamber 25, into which the material from thebeater roll is directly diverted, and

, the side of the chamber 25 oppositev the plate 9 is constituted by thevertical battle plate 26, of which there are a succession as set forth.The tops of the ballle plates 2G are below the top edge of the tub, andJfrom the top of the tub walls intermediate baille plates 27 extenddownwardly. The baile plates 26 and the outer wall ot' the tub with i sinner wall 2 comprise a series of compartments of which any number maybe provided. In each compartment is a refuse receptacle 28 the sides ofwhich taper downwardly, and each receptacle has an open bottom which mayhe closed-bya removable bottom plate 29, as best illustrated in Fig. 2,and the closure 29 is usually manipulated by means ot' a vhook rod30-which is engaged and disengaged assenso i 3 is a couch or take-oliroll 39 adapted to take the thickened stock off the screen roll 38. Theroll 39 is scraped by the doctor blade 40, and the thickened and cleanedstock is deposit-edfin the final chamber 41 shown in F ig. 4, from whichdchemiberby way of the outlet pipe 42 the stock may be conducted to achestor further refining machinery not shown. Towash olf the screen roll38 externally, the spray head 43 of any desired construction andarrangement is introduced as shown in. Fig. 1. lt will be noted furtherin Fig. 1 that a connection 44 is in communication with the interior ofthe screen roll 38, and by Way of connection 44 the rotary pump 45 takesthe water from the interior of the roll and forces the same pastvalve/46.

through the elevated pipe 47 into the mixing chamber 25, or elsewhereinto the tub as may be desired. bviously, the flow of returned water inpipe 47 may bedivided and delivered at any points found to beadvantageous inl a,l given operation.

lt is further believed to be within the scope of this invention toreplace the relatively wide bed plate 8 set forth in Fig. 1 by aperforated bedy plate 49 adapted to pass beaten stock downwardly into lareceiving box 50, which is in open communication with the mixing chamber25. It is believed to be equally the right of this applicant to providethe inner wall 2 of the tub at the turn of the wall as shown in Fig. 6,with a screen 51 for the passage of stock suitably beaten. The curvingand up-turning portion of the director plate 9 nea-r the roll 5 may beprovided ivith a perforated portion 48 for passing beaten stock into themixing chamber 25. Such additions are held by lthis applicant to beminor details, asl they are devices of well known structure and theiroperation and use is common knowledge in the industry to which thisinvention is designed to be applied. y

Considering Fig. 7 there will be noted adjacent to the beater roll 5 anadjustable doctor blade 52, which can be changed in position either tothe right or left or up or down as mai-*be chosen. There may be alsoapplied to he breaker roll 6 as set forth, an extractor' hood having aperforated face plate 54, and an internal spray pipev 55 to clean theperforated plate by Water spray. From the lower part ot the hood 53,pipe 5G conducts the fluent matter into the space between the slicepartition 16 and the beater roll as set o ut also in Fig. 8.'

Considering Fig. 10, there will be noted in the place of the doctorblade, an auxiliary roll '57 on across shaft 58 whereby it may berotated by means not shown but of any common elements, near the beaterroll 5 and in like direction. The blades 59 of the auxiliary roll inpassing near the blades of the beater roll take the material from thebeater roll and throw the same against and through the curved screen 60swept by blades 59 of the auxiliary roll and the screen is kept clear bythe movement of those blades. Such portions of the material not passedthrough the screen 6 0 are carried by the beater roll over the topthereof and under the hood 7 to be again passed under the beater roll.It will be observed in Fig. 1 0 that the curved screen 6() is removablysecured to the director plate 9 by the bolts 61., Any desired changingof the screen may thus be made.

In the operation of this invention, the stock beaten by the beater rollpasses into the mixing chamber and into one after the other of thesettling compartments described. The refuse materials are deposited inthose compartments as previously explained, and they are cleaned out oneat a time if need be and without interfering with the continuous runningof the apparatus tor any length ot time.

The cleaned and thickened stock is taken out at the end of the series ofsettling compartments, and the Water therefrom returned to the mixingchamber or tub. 1

The heavier materials are broken up by the breaker roll, and the lighterportions in circulation pass between the slice partitions 16 and 17, orover the latter and through the diii'erent recesses 21 adjusted asrequired for a .given operation.
